ALLAN-T. BENNETT, OF CHICAGO, ILLINOIS.

FIRE-PLACE.

EPECIPIGATION forming part of Letters Patent No. 342,776, dated June I, 1886.

Application filed November 20, 1884. Serial No. 148.450. (No model.)

To all whom it may concern:

Be it known that I, ALLAN T. BENNETT, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented a new and use fnl Fire-Place, of which the following is a specification.

My invention relates to an open grate with a reversible flue for heating rooms and buildings; and the objects of my invention are to secure in an open grate the advantages of a re versible flue, in order to economize the heat to the fullest possible extent,and to combine with the advantages of an open grate those of a hotair furnace. I attain these objects by means of the mechanism illustrated in the accompanying drawings, in which Figure 1 is a horizontal sectional view on line 3/ y of Fig. 2. Fig. 2 is a vertical sectional View on line :0 w of Fig. 1, and Fig. 3 is a vertical sectional view on line 2 z of Fig. 1.

Similar letters refer to similar parts throughout the several views.

In the drawings, G is the open grate, which receives the fuel for combustion. It is provided with a flue which opens directly into the flue A, as shown in Fig. 3.

A is the direct line to the chimney or smokestack M, but which may be closed by means of the damper I.

B is the flue which conveys the smoke from the flue A to the chimney M when the fine A is closed by the damper I.

C is a heating-chamber beneath the ash-pan D, which pan is connected by means of the tube F with the ash-pit beneath the chamber C. The chamber C opens into the fines A and B beneath the air-chamber E and in front of the tube F, and it serves as a continuation of the flue A.

H is a partition in chamber C, extending from the tube F to the back side of C, thus causing the smoke and hot gases to pass through the chamber 0 in front of the tube F, in order to pass from flue A to flue B, as more fully described below.

K is the floor of the room.

E E is an air-chamber surrounding the grate and flues A and B, as shown in the drawings. The cool air enters the chamber E E above the floor and beneath the front of the grate, as shown in Fig. 3, passing beneath the ash-pan D and into the chamber E E, where it becomes heated by the radiation from the grate'and from the fines Aand B, and passes upward and outinto 'the room beneath the mantel, as shown by the to another instead of being taken out into the room.

The partition H could be removed if at any time found desirableand the smoke would then pass directly from the line A to the due B.

The operation of the tines A and B is as follows: hen the damper I is turned back from flue A, the smoke and heated gases from the grate pass directly into the chimney M when there is a direct draft. \Vhen the damper I closes the top of the flue A, as shown in Fig. 3, the smoke from the combustionchamber passes into flue A, and thence downward into the chamber C and forward around the tube F, and thence backward into the flue B, and thence into the chimney. In this course much of the heat from the smoke and heated gases will be taken up by the air in chamber E E and conveyed into the room, as above described.

.In cases where the grate is not provided with the partition H, the movement of the smoke from flue A to flue B would be more direct, but otherwise the same.

Having thus described my invention,what I claim to have invented, and desire to secure by Letters Patent, is

1. An open fire-place provided with a grate to receive the fuel, an ash-pan beneath the same, in combination with a casing surrounding said fire-place, flues A B, extending down in rear of the fire-place and horizontally beneath the ash-pan,connecting at the front with a space between such fines and the fire-place, the said flue A connected with the fire-place and the flue B withthe uptake, whereby an air-chamber between the fire-place and the.

casing is formed, and an opening thereto below the ash-pan, substantially as described.

2. An open fire-place provided with a grate to receive the fuel, in combination with a flue leading from the top of the fire-place back and connecting with an ascending and descending flue, A and B, the descending flue A extending down and running horizontally under the fireplace beneath the ash-pan chamber and below the floor on which the fire-place rests, forming a heating-chambelyC, an air-chamber, E, surrounding the fire-place and the flues, an inlet-passage lor the outer air between the said chamber G and the ash-pan, an outlet-passage for hot air leading from chamber E into the room to be heated, and a suitable damper for admitting the products of combustion di- 15 rectly to the chimney or turning them down ALLAN '1.
